SMOKE-BURNING ATTACHMENT FOR FURNACES.

SPECIFICATION forming part of Letters Patent No. 297,845, dated April 29, 1884.

Application filed December 29, 1883. (No model.)

inSmoke-Burning Attachments for Furnaces;

and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to-make and use the same, reference being had to the accompanying drawings, which form a part of this specification, and in which- Figurel is a side view of our improved smoke-consuming attachment, showing it i l position over the fire-place of a steam-boiler, with the wall of the fire-place broken away. Fig. 2 is a longitudinal vertical section of the attachment, and Fig. 3 is a cross-section of the same.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to smoke-consuming attachments for fire-places for steam boilers and similar fire-places; and it consists in the improved construction and combination ,of parts of the same, as hereinafter more fully described and claimed. 7 r

In the accompanying drawings, the letterA indicates the fire-place, B the boiler, and O the front wall of the fire-place. A nozzle, D, is inserted through the front wall of the fireplace a short distance below the under side of the boilersay six inches-which nozzle is preferably cylindrical, narrowing down to a point, through which the fluids passing through the nozzle pass.

E is a water-tank, having a pipe, F, leading down to the nozzle, which it enters at its rear end through a pipe, Gr, bending downward at its outer end a short distance from the point or aperture of the nozzle. A steam-pipe, H,

contracting at its outer end, passes into the nozzle below the water-pipe, opening immedi- 5 ately below the downwardly-bent end I of the water-pipe, and both the pipes are provided with suitable stop-cocks, J, by which the flow of steam and water may be regulated. It will now be seen that as the steam and water are turned on it will pass in a spray over the fire in the fire-place, precipitating the soot and other solid products of combustion upon the fire, where they will again be consumed, thus depriving the smoke of all its solid contents, the

mixed stream of steam and water accomplishing a more perfect combustion than either steam or water alone. By having the end of the Water-pipe bent downward immediately above the end of the steam-pipe, the streamof water is struck by the jet of steam and perfectly atomized, falling in an even shower over the entire fireplace, thus consuming, or rather precipitating, every solid particle of smoke.

Having thus described our invention, we

claim and desire to secure by Letters Patent of the United States The smoke-consuming attachment for steamboilerfurnaces and similar furnaces, consisting of a cylindrical nozzle contracting at its perforated end, a steam-pipe having its open end contracted, and a water-pipe having its outer open end bent downward over the opening of the steam-pipe, as and for the purpose shown and set forth.

In testimony that we claim the foregoing as 1 our own we havehereunto afifixed our signaturesin presence of two witnesses.
